    Why Use Chicken IgY?

  • Here are top 5 reasons:

    1. Higher titres against highly conserved mammalian gene products

    2. Double immunostaining is easier to perform

    3. Animal-friendly -- we purify the antibodies from eggs, not serum

    4. Large quantities of antibody - faster and cheaper

    5. Nearly unlimited quantities (again, because the antibodies come from eggs)

What is the difference between the terms “IgY Fraction” and “Affinity-Purified Antibody Fraction”?

IgY fraction refers to the total complement of antibodies circulating in the hen’s serum when the egg was produced. Affinity-purified antibody fraction refers to only those antibodies that bind to the antigen (or peptide) with high affinity. These affinity-purified antibodies typically correspond to 0.5%-2.0% of the total complement of circulating antibodies.
